Charging and Discharging a Capacitor
The larger capacitor also ends up with a greater amount of charge on its plates. This is because fringe field magnitude is inversely proportional to plate area, as shown in the equation below. In the first, short time interval, roughly equal quantities of charge will accumulate on the capacitor plates.

21.6 DC Circuits Containing Resistors and Capacitors
A small resistance R R allows the capacitor to discharge in a small time, since the current is larger. Similarly, a small capacitance requires less time to discharge, since less charge is stored. In the first time interval τ = RC τ = RC after the switch is closed, the voltage falls to 0.368 of its initial value, since V = V 0 ⋅ e − 1 = 0 . 368 V 0 V = V 0 ⋅ e − 1 = 0 . 368 V 0 .
